I hope so, too :) I have the same b4312 dma errors. $ dmesg | tail -7 Registered led device: b43-phy0::rx Registered led device: b43-phy0::radio __ratelimit: 8 callbacks suppressed b43-phy0 ERROR: Fatal DMA error: 0x00000400, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000 b43-phy0: Controller RESET (DMA error) ... b43-phy0: Controller restarted b43-phy0: Controller restarted I built b43 from daily tarball compat-wireless-2009-09-07,tar.bz2 . Card: B4312 low-power phy, BCM4312 802.11b/g [14e4:4315] (rev 01) (on a Dell Mini 10, N-Series). Kernel: 2.6.31-rc9 . 32bit. Hyperthreading Patch: I assume this means http://bu3sch.de/patches/wireless-testing/20090816-1535/patches/002-b43-threaded-irq-handler.patch I did not actually apply this patch, i just checked the source for a few lines added in this patch and assumed it is merged in the daily tarball already. Is this correct? Firmware: Debian Sid. b43-fwcutter version 012 comes with 4.150 fw it seems. On Openwrt I only found the afore mentioned "v478" firmware http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2 . b43-fwcutter does not work with it. Is there documentation as to how to extract newer firmware? I couldn't find the v5xx firmware. It's nowhere on your sites, is it? Let me know if there is something I can do to help, but be aware I am not knowledgeable with linux-wireless, it's my first WLAN Device in Years. And your site is a bit.. confused.. errm confusing ;) Cheers, Markus
